The Külliye of Damat İbrahim Paşa is the architectural centrepiece of old Nevşehir, built in the 1720s by the city's most famous son, the Ottoman grand vizier Ibrahim Paşa. The complex consists of a mosque, a medrese (religious school), a library, and a hammam, all built in the Ottoman classical style.
The mosque is the finest building in Nevşehir, with a well-proportioned facade and interior. The attached medrese building has been converted to other uses but the courtyard can be entered. The complex is in the old quarter below the castle, making it a natural stop on the walk up to the fortress.
